1.1 Product introduction
ZR - 1000 type mask bacteria filtration efficiency key performance
indicators (BFE) detector not only conforms to the requirements of
medical surgical masks technology YY0469-2011 appendix B in the
test method for filter efficiency (BFE) bacteria first B. 1.1 the
requirement of test instruments, but also conforms to the American
society for testing material ASTMF2100, ASTMF2101, the requirements
of the European EN14683 standards, innovative improvements were
made on the basis of this, with double pneumatic contrast sampling
method at the same time, improve the precision of sampling,It is
suitable for measuring and testing departments, scientific research
institutes, mask manufacturers and other relevant departments to
test the performance of mask bacterial filtration efficiency.
